Just supplementing with Calcium without the cofactors
such as Vitamin D, Magnesium, Vitamin K2, and Boron, appears to INCREASE rather than decrease fractures of some bone
and cause many other health problems (Cardiovascular, Kidney stones, prostate cancer, etc)
The following 2010 paper identified the problems with the Calcium and bone fracture studies
Many other studies shown at the bottom of this page support his thesis.

Credible evidence that calcium supplements reduce the risk of vertebral, nonvertebral, or hip fractures is lacking.
Flaws in study design and execution such as inclusion of calcium-replete individuals, high dropout rates, and poor compliance preclude testing the hypothesis that calcium deficiency increases fracture rates or that calcium supplements reduce them.
Intent-to-treat analyses of individual trials have failed to detect antifracture efficacy.
Post hoc analyses of subgroups with a low calcium intake and per-protocol analyses of compliers have reported fewer fractures in the supplemented groups.
However, this may be the result of confounding by violation of randomization; compliers to placebo have a lower morbidity and mortality than noncompliers.
Higher hip fracture rates and cardiac mortality in patients receiving calcium supplements, as reported in some studies, may also be due to factors other than supplementation.
Hypothesis testing requires that a cohort be stratified into calcium-deficient and calcium-replete groups, with each person randomized to a supplement or placebo.
This design quantifies the risk of fracture attributable to calcium deficiency and any benefit that supplementation confers in the calcium-deficient and calcium-replete groups. To regard a calcium-deficient arm as unethical begs the question.
Consensus statements that support the widespread use of calcium are opinion-based; they accept claims of beneficial effects despite flaws in study design, execution, and analysis; and they reject reported adverse effects because of them.
Until well designed, well executed, and well analyzed studies demonstrate a net benefit in morbidity, mortality, and cost, recommendations supporting the widespread use of calcium supplementation remain belief-based and not evidence-based.

Surprisingly, he found that countries with low intakes of calcium actually had lower rates of hip fracture and countries with high intakes of calcium had higher rates of fracture.
For men >68, the higher rate of calcium intake resulted in a 7X increase in prostate cancer risk.

Since 1975, 136 trials have explored calcium’s effects on osteoporotic fracture risk.
Two-thirds of these studies show that high calcium intake yields no reduction in the number of fractures
Another Harvard team analyzed seven trials that followed 170,991 women for several years and found “no association between total calcium intake and [reduced] hip fracture risk.”
